Extend CoSec 8.0 with Spring beans - AttributeProvider (external ext.* attributes fetched per request), MembershipProvider (roles and attached policies kept outside tokens), DecisionListener (audit, metrics, alerts), RateLimiter (where permits are counted) and Authenticator (how tokens or API keys are verified). Use when the policy language and built-in features cannot express a requirement. Do not use for writing policy documents.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Extending CoSec Extend only after confirming that a document cannot express the rule: conditions, bindings and rate limit rules cover most needs (use `$cosec-policy-author`). CoSec 7.x custom action and condition matchers (`ActionMatcherFactory`, `ConditionMatcherFactory`) have no 8.0 equivalent: conditions are a fixed AST, and new facts enter evaluation as external attributes. Human-facing reference: https://cosec.ahoo.me/architecture/extending. In a CoSec checkout the ports live in `core/spi/src/main/kotlin/me/ahoo/cosec/spi/` (`attribute/`, `authn/`, `membership/`, `ratelimit/`, `token/`, `apikey/`, `snapshot/`, `audit/`, `id/`; module `cosec-spi`, which depends only on the model, the contracts, the stability markers and coroutines), and the ones that carry runtime types in `core/runtime/src/main/kotlin/me/ahoo/cosec/runtime/` (`event/`, `attribute/` for `BlacklistSource`); the starter wires them in `host/spring-boot/src/main/kotlin/me/ahoo/cosec/spring/boot/starter/pipeline/CoSecPipelineAutoConfiguration.kt` and `CoSecPipelineIntegrationAutoConfiguration.kt`. A library that only implements a `cosec-spi` port depends on …

How to install
mdr add ahoo-wang/skills/cosec-custom-matcher@sha256:9ad4e1de578084adThe line at the top of this page pins the label git:20261029.b6d8370, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
